The updated command uses a modeless dialog box so you can leave it open while you do other work.
You can use this command to perform the following analysis types:
Resize Pipes and Reset Inverts: Analyzes the flow through the pipes, and then resizes the pipes and resets inverts to accommodate the flow.
Compute Energy and Hydraulic Grade Lines: Calculates the energy and hydraulic grade lines, and reports whether each line in the system is in a normal state, surcharged, or flooded.
Inlet Analysis: Analyzes the capacity of the inlets and reports the flow, depth, and spread at each inlet.
